OS Version: 7.1.2 (Nexus 6P)

Other browsers tested:
  I believe this works fine pre-WebAPK but haven't verified recently.

What steps will reproduce the problem?
1. Add Twitter pwa to home screen using Chrome dev
2. Wait for a notification
3. Ensure Twitter light and chrome dev are not running (kill Twitter light in task switcher)
4. Click on notification 

What is the expected result?
Twitter light opens to page referenced by notification

What happens instead of that?
Twitter light opens to the last page I was looking at

If instead I ensure Twitter light is running when I activate the notification it works fine.

Please provide any additional information below. Attach a screenshot if
possible.
